Vizio M-Series 4k Smart TV 2021 Review & Buying Guide

The Quantum Vizio M-Series provides the best smart television you’ll get for less than $1,000. Together with Dolby Vision assistance, it has remarkable picture quality and excellent HDR performance with local dimming and color boosting quantum dot technology.

A built-in Chromecast brings up a wide variety of applications and facilities, and the new SmartCast software contains Apple AirPlay2 and HomeKit help, rendering it just as useful for iOS users.

Design

The Vizio M-Series Quantum’s general design is mainly unchanged from the past year, but this is certainly an instance where nothing especially required to change. The top and sides of the screen are surrounded by slim black bezels, with a wider bezel running along the bottom. A silver Vizio logo, the only important aspect on the front of the set, is in the bottom right corner of this.

Without the stand, the TV covers 57.3 x 35.6 x 2.8 inches. Due to a patterned texture that covers the back of the cabinet, the back of the TV isn’t as flat as you’ll see on most TVs. The design of the TV is reasonably sturdy, made of black plastic, and weighs 53.4 pounds.

Picture Quality

Aside from the viewing angle and poor input upscaling the Vizio M Series has a good picture quality. Its contrast ratio maintains a higher than average score for deeply colored blacks. The M Series also has a good color gamut, and though it is not truly “wide” the remaining colors onscreen are saturated nicely as well.

The brightness is a nice side note for the M Series. Glare is fought off as well as reflections in most cases.

Performance

The M-Series Quantum offers some really outstanding performance for a collection that buys for less than $1,000 with a combination of quantum dots to increase brightness and color and a complete range of local dimming for deeper blacks and brighter brights.

Watching a movie filled with vivid colors and quick action, like Spider-Man: Homecoming, I was happy to see that the M658-G1 designs appeared real to reality. The Washington Monument’s daytime shots were packed with red, white and blue flags, beautiful green landscaping and lots of moving peoples, and it all appeared smooth and vivid.

High dynamic (HDR) content also feels good on the M658-G1 with help for both HDR10 and Dolby Vision. A Spider-Man night battle scene with a monster on a dull lake was dull enough but punctuated with vivid fire and glowing lights. And unlike the results we saw on the P-Series Quantum PQ65-F1 last year (Vizio’s first quantum-dot display), the person backlighting areas did not trigger the kind of separate flaring that was so common on that collection.

Contrast Ratio

Contrast Ratio: ~4600:1

Bottom Line: Above Average
as many others will point out, the 2018 version of the Vizio M Series technically has a worse contrast ratio, but in reality, it is still good. This is because the overall performance is the key standard here which the M Series does well by.

Local Dimming

Local Dimming: Yes
Backlight: Full-Array (FALD)
Bottom Line: Below Average
As with many other smart TVs from 2018, the M Series has poor local dimming features. The “Xtreme Black Engine Plus” in no way actually enhances the contrast ratio and instead leads to blooming/ clouding around the effected areas. I recommend that you leave this particular setting off or medium at most on the Vizio M Series.

Viewing Angle

Viewing Angle:~23°
Bottom Line: Narrow, but Expected
Both the M55-F0 and M65-F0 have VA (vertically-aligned) panels. These panels are known to have better better contrast ratios while sacrificing their viewing angles. So in the case of the Vizio M Series, you’re best off expecting this result as to not be let down. Though the picture holds up for a little bit when sitting to the side, I estimate anything more than ~23° is just a different picture at that point.

Input Upscaling

480p: Blocky, but as expected with most methods of upscaling work in a way that produces ‘blocky’ results.
720p: Scenes are softer than desired, but this is true for many of the best 2018 TVs right now.
1080p:. Refined details that are quite sharp while retaining the quality.
4K: Great quality.
Bottom Line: Textbook
Content of all levels look quite good on the M Series TV, but 480p will take some getting used to as it is a bit blockier than most would like.

Color Gamut

DCI P3 Color Space

DCI P3 xy: ~75%
DCI P3 uv: ~80%
Rec 2020 Color Space

Rec 2020 xy: ~55%
Rec 2020 uv: ~60%
Wide Color Gamut: No
Bottom Line: Good
Even though the M Series does not “truly” have a wide color gamut, that’s not to say the picture quality is not good. With my Vizio M Series TV review, I found the supported colors to be properly saturated in contrast to the deep blacks or bright whites in the picture. Though, with the newer smart TVs being released as the year goes on, it would have been nice to some extra oomf from the M series.

Motion Handling

A fast response time is the biggest thing the Vizio M Series 2018 has going for it under its motion handling. The trail is quite little and the eye tracking is nicely reduced, but the 24p playback is not well supported while the 60 Hz refresh rate doesn’t allow for motion interpolation, if any at all.

Motion Blur

Response Time:~13 ms
Bottom Line: Great
In addition to to helping fast moving content look smother the response time of the M Series combines well with the low input lag it also has making it a solid choice as one of the best TV for video games. You can notice the effect of the response most largely with sports or movies.

24p Playback
24p: Yes
24p via 60p: No
24p via 60i: No
Bottom Line: Poor
The M55-F0 and M65-F0 both struggle to remove judder from most sources. The one saving grace is that the built-in applications help to remove judder. For instance, on the Vizio M Series, if you are using the Netflix application, you are likely judder free as it is a application on the smart TV itself. Judder can be a bit of a hit or miss type of thing with most people so please let me know if you find anything different.

Motion Interpolation

30 FPS: No
60 FPS: No
Soap Opera Effect: No
Bottom Line: Poor
There are no settings to further smooth the picture of the M Series. This is a bit of an odd feature for a smart TV to not have, but in my opinion it is not needed either.

Inputs

After finishing my Vizio M Series TV review, I noticed the inputs had improved the most compared to other metrics. The input lag has lower dramatically for gaming, the M Series now has a TV Tuner, and it now has more support of the common PC resolutions that the previous models did not have. These are very good adjustments that Vizio has made for the M Series.

All Inputs
HDMI : 4
USB : 1
Digital Optical Audio Out : 1
Analog Audio Out RCA : 1
Component In : 1 (shared)
Composite In : 1 (shared)
Tuner (Cable/Ant) : 1
Ethernet : 1
For every one that nearly threw their previous M Series out of a window, please note there is now a TV Tuner.

Supported Resolutions
1080p @ 60Hz @ 4:4:4: Yes
1080p @ 120Hz: No
4k @ 30Hz @ 4:4:4: Yes
4k @ 60Hz: Yes
4k @ 60Hz @ 4:4:4: Yes
Bottom Line: Great
All of the commons resolutions are supported by the M Series aside from 1080p @ 120 Hz. This is because the M Series only has a refresh rate of 60 Hz.

VESA Pattern

what-is-a-vesa-pattern

M55-F0: 200 x 200 mm
M65-F0: 400 x 200 mm
Input Lag

Best Input Lag: ~20 ms

Bottom Line: Great
With a input lag as low as this, the Vizio M Series is potentially making a case for the best TV for video games. All kinds of games just wok better when you can properly react to the incoming information and with the well budgeted price of the M Series, can you go wrong? One thing to note is that the ‘Game Low Latency’ settings will need to be enabled to lower the input lag. Aside from that, you’re off to the races.

Input Features

HDR10: Yes
Dolby Vision: Yes
5.1 ARC Dolby Digital: Yes
5.1 Passthrough ARC DTS: Yes
5.1 Optical Dolby Digital: Yes
5.1 Optical DTS: Yes
ARC: Yes (HDMI 1)
Even though the Vizio M Series 2018 does not have a ‘wide’ color gamut, HDR10 is still supported.

Smart Features:

The Vizio M Series 2018 runs the Google SmartCast operating system. In terms of overall functionality it is quite good. The applications that the M Series has work well and they are alwas easy to find, but that about the most of it. You cannot download more apps or add extra functions you might find useful.

Operating System
google-smart-cast-vizio-trt

Operating System: SmartCast Powered by Google
Bottom Line: Smooth, but Basic
The main attractions of the SmartCast platform is that you can stream content (photos, music, or videos) from just about any type of device you want to. I found this particularly useful when having friends over. Sharing videos through YouTube, queuing up songs through Spotfiy or exchanging photos from our phones is a breeze.

The M Series variants (M55-F0 and M65-F0) do not come with advertisements built into their smart features. Personally, this is a huge plus. Immersion is a key element when using a smart TV and the ads take away from that experience. You will find some suggested content based on prior TV usage, but that about the extent of what the M Series will bother you with.

Conclusion

Over the past couple of years, Vizio has produced significant progress, and the quantum-dot push of this year has maintained that momentum by providing an outstanding show with great value.

The M-Series Quantum provides excellent brightness and HDR efficiency, strong color and image quality, and better-than-average sound for a collection that is probably the middle kid in Vizio’s lineup. The Vizio M-Series Quantum 65-inch (M658-G1) provides you a lot to know for its under-$1,000 costs with a changing smart-TV system and plenty of interfaces and features.
